Newbie: use of built-in exceptions

[Rui Maciel]

Are there any guidelines on the use (and abuse) of Python's built-in exceptions, telling where
it's ok to raise them and where it's preferable to define custom exceptions instead?


Thanks in advance,
Rui Maciel

There are no rules. You should use common sense instead: if the
exception fits your needs (eg. ValueError when incorrect output
occurs) then use it.

Ok, thanks for the tip.
